400 series Wear resistant steel plate including some types steel that Brinell hardness up to 400 (HBW). The number 400 is the Brinell hardness value (HB value), which is a broad concept that the surface hardness of the product usually reaches 360 ~ 450HB.The hardness of GB NM400 can be 360-420. Slight variations in chemistry are present depending on the steel producing mill and these wear resistant steel plates offer excellent resistance against slide wear, rub wear, heavy wear and withstand high impact stresses even at extremely low temperatures, can be used in the manufacture of quarries, mining, truck-trailer, bucket components, construction equipment and concrete industries.
